FASTENER Joseph D. Tessier, Worcester, Mass. Applic'ationApril 29, 1943,--Serial-No. tag-e53 V 7 Claims.

This invention relates in general to fasteners and particularly to fasteners to be applied to storm Windows for quickly and positively securing thest'orrn sash to the permanent window frame.

Qbje'cts of the invention include the provision ofa'positivelocking'fastener for securing a movable paft'to "a relatively'fi'xed part such as for instancein doors, windows, etc, and more especially for securing storm sash to window frames; the provisio'n of easily and 'quickly Operable locking fasteners which are positive in type and which are rugged in construction and" easy and relatively inexpensive in the manufacture thereof.

Further objects of the invention include a fastener comprising a base plate, a locking lever element which is pivoted to the base plate so that it may be swung from an unlocked condition wherein the lever is contained mostly within the confines of the base plate, to a locking position wherein the lever overhangs the plate laterally thereof, and including a positive locking member cooperating with cam-like elements on the locking lever for depressing the latter toward the base plate into positive engagement with a member to be locked.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing in which Fig. 1 is a plan view of my invention showing the same in looking position;

Fig. 2 is a view showing the fastener in unlocked position; and

Fig. 3 is a view partly in section and showing the fastener in end elevation.

For purposes of illustration the present invention. is shown as applied to a storm sash frame l having a window pane l2 secured thereto and forming a part thereof in the usual manner. The storm sash is to be secured in tight condition to a window frame Hi. It is to be understood, however, that this invention may be applied to applications other than the storm window illustrated.

The fastener comprises a base plate l8 which has a width such as to be included within the storm sash frame HI and a pair of set screws 18 may be employed to secure the base plate to the storm sash. Plate 16 is provided at its ends with turned up ears- 20, these ears providing bearings for a generally U-shaped handle 22 which swings on the ears 2D. A finger piece 24 may be utilized if desired for swinging the handle on its pivots. It will be noted that handle 22 has a pair of straight so 10 6 h hligggydlel tgda e [1 handle element will engage the cam surfaces 35 to depress the leg 32 to a greater degree the further the handle 22 is swung to the right in Fig. 3. This results in depressing the free end of leg 32, as for instance, from the dotted line position shown at 38 in Fig. 3 to the full line position therein, and for this reason variations in thick-v ness of the window frame I4 are accounted for. Due to the friction between handle 22 and cam surfaces 36, handle 22 will remain where placed especially in any position to the right of a vertical position of the handle as seen in Fig. 3.

The construction above described provides a simple and easily manufactured locking fastener which is extremely positive in its action and which will always hold the storm sash H1, or other element firmly and tightly against the frame M or similar element. The fastener includes only two stamped metal parts and the handle 22, the latter being made of wire in an obvious manner, and

it will thus be seen that I have provided a simple and efficient locking fastener for general utility purposes as well as for securing storm sash.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is: 1. In a device of the class described, a base plate, a locking member mounted on said plate, said member having a resilient free-ended leg disposable outside the limits of said plate to overlie an element to be locked, means on said plate for impinging on and clamping said leg directly against said element, and means independent of the clamping means pivoting the locking memher to said plate.

2. In a device of the class described, a base plate, a locking member pivotally mounted on said plate, said member having a resilient. freeended leg having a fiat portion disposable in part outside the limits of said plate to overlie an element to be locked, and means on said plate for directl clamping the flat portion of said leg against said element, there being a cam on the leg, and said means comprising a movable element pivoted to the base plate and having an arm cooperating with the cam to depress said leg into contact with the first named element.

3. In a device of the class described, a base plate to be secured to an element, a movable member on the plate, a locking member pivotally mounted on the plate, a free-ended resilient leg on the locking member, said leg having a fiat portion; the locking member disposable to position said leg at least largely within the confines of the plate in unlocked condition of the device or selectively in a locking condition wherein the fiat portion of the leg extends laterally beyond the plate to overlie a second element to which the first mentioned element is to be locked, cam

means on the fiat portion of the leg, said movable member straddling the resilient leg and engaging the cam means to depress the leg to clamp the second member.

4. As an article of manufacture, a plate, a U- shaped member having a long resilient leg and a shorter leg, the latter being pivoted to the plate so said long leg may be swung relative to the plate, a cam on the longv leg, and means on the plate cooperating with the cam to depress said long leg, said means comprising a bail pivoted to the plate and engaging the cam.

5. As an article of manufacture, a plate adapted to be secured to an element, a Ushaped member having a short and a long free-ended leg, a pivot connection between the short leg and the plate, said long leg extending beyond the lateral confines of the plate in one position, cam surfaces on the long leg, a wire member pivoted at its ends to the plate, portions of the handle cooperating with the cam surfaces to directly depress the long leg at its free end towards the plate, said wire member straddling the long leg to engage the cam surfaces, and a handle on said wire member.

6. A fastening device comprising a plate, a pair of ears at spaced points thereon, a handle pivoted in said ears and extending across the plate, a U-shaped member having ashort leg and a spaced longer free-ended resilient leg, said short leg being pivoted to the plate intermediately of the ears, said handle being swingable from below the longer leg up over the same, and a cam on the longer leg in position to be engaged by said handle to depress the long leg at its free end towards the plate.

7. A fastener comprising a plate, a pair of ears thereon, a bail pivoted in said ears, a U-shaped clamping member pivoted on the plate between the ears, said member being pivotable when the bail is down in relatively flat relation to the plate, said bail being swingable up over the member in clamping position thereof, a cam on one leg of the clamping member, said bail engaging the arm to depress the said one leg.
